Synopsis
--------

Managing NFS export on Unity storage system includes- Create new NFS export, Modify NFS export attributes, Display NFS export details, Delete NFS export.



Requirements
------------
The below requirements are needed on the host that executes this module.

- A Dell Unity Storage device version 5.1 or later.
- Ansible-core 2.13 or later.
- Python 3.9, 3.10 or 3.11.
- Storops Python SDK 1.2.11.



Parameters
----------

  nfs_export_name (optional, str, None)
    Name of the nfs export.

    Mandatory for create operation.

    Specify either *nfs_export_name* or *nfs_export_id* (but not both) for any operation.


  nfs_export_id (optional, str, None)
    ID of the nfs export.

    This is a unique ID generated by Unity storage system.


  filesystem_name (optional, str, None)
    Name of the filesystem for which NFS export will be created.

    Either filesystem or snapshot is required for creation of the NFS.

    If *filesystem_name* is specified, then *nas_server* is required to uniquely identify the filesystem.

    If filesystem parameter is provided, then snapshot cannot be specified.


  filesystem_id (optional, str, None)
    ID of the filesystem.

    This is a unique ID generated by Unity storage system.


  snapshot_name (optional, str, None)
    Name of the snapshot for which NFS export will be created.

    Either filesystem or snapshot is required for creation of the NFS export.

    If snapshot parameter is provided, then filesystem cannot be specified.


  snapshot_id (optional, str, None)
    ID of the snapshot.

    This is a unique ID generated by Unity storage system.


  nas_server_name (optional, str, None)

    ID of the NAS server on which filesystem will be hosted.


  path (optional, str, None)
    Local path to export relative to the NAS server root.

    With NFS, each export of a file_system or file_snap must have a unique local path.

    Mandatory while creating NFS export.


  description (optional, str, None)
    Description of the NFS export.

    Optional parameter when creating a NFS export.

    To modify description, pass the new value in *description* field.

    To remove description, pass the empty value in *description* field.


  host_state (optional, str, None)
    Define whether the hosts can access the NFS export.

    Required when adding or removing access of hosts from the export.
